I have a 2011 GM Nav Disc Version 6.0c (Part #20940248). It will work in the GM factory Nav radios from the 2007-2011 Avalanche, Suburban, Tahoe, Yukon, H2, Silverado, Sierra, Cadillac DTS & SRX. It has been used in a GM OEM Nav radio but is in mint condition with no sctratches or marks. I also have the OEM case as well. Please double check your Nav radio just to make sure this disc will work in it. You can find out fitment here. http://www.gmnavdisc.com/ $50.00 OBO shipped. Please, No Lowballs.
